END CLIP OR BEARING-PLATE FOR SEMIELLIPTIC SPRINGS.

SPECIFICATION forming part of Letters Patent No. 737, dated p m r 1903Application filed July 22,1903. Serial No. 166,508. (No model.)

T0 (1, whom it may concern.-

Be it known that 1, JOHN H. EVANS, a citizen of the United States,residing at Oak Lane, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in EndClips or Bearing-Plates for Semielliptic Springs, of which the followingis a specification.

My invention has relation ,to semielliptic springs in conjunction withend clips orbearing-plates adapted to detachably fit the ends of suchsemielliptic springs for locomotives, tenders, &c., on which the load isusually supported; and in such connection it relates to the constructionof the springs and arrangement of the end clips or bearing-plates forsuch semielliptic springs for locomotives and tenders, as well as othersomewhat similar types of springs to which such clips or bearingplatesare equally applicable,the clips or bearing-plates being so arranged asto be readily applied to and detached from the ends of the springs andthe ends of the springs and plates provided with mechanical meansadapted to sustain or support the load.

The nature and scope of my present invention will be more fullyunderstood from the following description, taken in connection with theaccompanying drawings, forming part hereof, in which- Figure 1 is asideelevational view of a semielliptic spring with detachable end clips orbearing-plates of my invention shown in application to the respectiveends of the uppermost leaf of the spring. Fig. 2 is a perspective view,in broken section, of one end portion of a semielliptielocomotive-spring, showing the slotted clip or bearingplate mounted onthe uppermost leaf of the spring in looking engagement with the spring,and a hanger extending through the slot of said clip and leaves of thespring, and a pin arranged transversely of the hanger and in engagementwith a recess in the shouldered portion of the clip in its lockedposition. Fig. 3 is a similar View of a modified form of atender-spring, showing the recessed and shouldered end clip orbearing-plate in e11- gagement with the lowermost leaf of the spring andwith a saddle-hanger adapted to span the end of the spring and clip forsupporting the same in required position to sustain the load; and Fig. 4is a similar View of a slightly-modified form of the end of atender-spring and detachable clip or bearingplate in engagement withsuch a locomotivetender spring and adapted to be spanned by asaddle-hanger of the same type as illustrated in Fig. 3 or of any othersuitable type.

Referring to the drawings, A represents a semielliptic spring of whichthe various leaves are locked together by means of a band in anysuitable manner.

a in Figs. 1 and 2 is the uppermost leaf of the spring, and in Figs. andat a represents the lowermost leaf thereof. The main leaf ais curvedover ormade in the form of a gooseneck at each end, as at a.

B in Figs. 1 and 2 is the end clip or bearingplate with a fiat base, andwhich clip or plate is made tapering, as at b, to a recess 1) and taperstherefrom, as at W, to a rounded end 12 which corresponds in shape tothe gooseneck or turned-over end a" of the leaf a of the spring A inorder that the clip or plateB may be readily slid sidewise to place intothe end of the leaf a of the spring A and be held to place thereby onsaid spring. The clip or plate B is slotted, as at I), through the bodythereof, and this slot extends, preferably, through certain of theleaves of the spring A, so that a hanger or strap 0 may be insertedcarrying a pin 0, adapted to engage in the recess 1) of the inclinedshouldered clip or plate B. The clip or plate is made preferably ofmalleable or wrought iron, or it may be made of any other preferredmaterial. It can be economically made and readily applied to a springyaswell as readily detached therefrom, when the dead-load on the spring isreleased or lessened in case of repairs with out injuring any parts byresort to tools, so that neither end clips or plates or leaves of thespring can be impaired by the assembling or separating of the parts ofthe spring, thereby especially adapting the clips or plates for use insemielliptic or similar types of springs used in locomotives and tendersof motivcpower appliances.

In Figs. 3 and 4 is shown a spring having the turned-over or gooseneckends a, shown formed atthe respective ends of the lowermost leaf of theseries of leaves of the spring, in which the clip or plate B isshouldered or rounded at b at one end, so as to correspond in shape withand to fit the space formed by the gooseneck or turned-over end a of theleaf a of the spring A, and the clip or plate B has a flat face 6 and atthe opposite end is provided a projection b with a round taperingsurface I), to the base of the clip or plate 13. The same is true of theclip of Fig. 4:, except that the rounded end I) at the right of the clipor plate B is slightly modified in shape, so as to correspond with theparticular shape of the curved end a of the leaf a of the spring A.

Having thus described the nature and obj ects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. A spring provided with leaves, whereof one has gooseneck shape orturned-over ends, in combination with a clip or plate detachably fittingeach of said ends and supported on said leaf, and means for supportingsaid spring and clip or plate.

2. A spring provided with leaves, whereof one leaf is provided withgooseneck shape or turned-over ends, in combination with a clip or platedetachably fitted sidewise into each of said ends and supported inposition on the surface of said leaf, and means for supporting saidspring and clip or plate in required load-carrying position.

3. A spring provided with leaves, whereof one of said leaves hasturned-over ends, in

combination with a complemental clip or bearing-plate at each endresting thereon and in engagement with said ends, and means eX- tendingthrough the body of said clip or plate and spring and having a deviceadapted to engage with said clip or plate.

4. A spring provided with leaves, whereof one has turned-over ends, incombination with a clip or plate with a complemental end adapted to beslid into contact with each end of said spring and bearupon the surfacethereof, and means for supporting said spring and clip or plate inrequired operative or load-carrying position. v

5; A spring provided with leaves, whereof one has a turned-over orcurved end, in combination with a clip or plate provided with acomplemental end and opposite shouldered end and a saddle-shaped hangeradapted to support said clip or plate and spring in required position.

6. A spring provided with a turned-over or curved end, in combinationwith a clip or plate having a complemental shaped end and recessshouldered body having a slot extending therethrough and said spring anda hanger or strap with a pin engaging said slot and recess of theshouldered body of said clip or plate.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.

JOHN H. EVANS.
